Eclipse Web and J2EE Development



My Background

■ Software Developer at IBM Toronto Lab– Focus on Web Service and XML Tools– Rational Application Developer V6– WebSphere Studio Application Developer V5

■ Eclipse Web Tools Platform Project – Ecosystem Lead– Work on validators, URI Resolver framework, Cache

■ Committer on Apache Woden Project– Building a WSDL 2.0 validating parser



J2EE Scenario

■ Java class accesses data from a database

■ Java class exposed as a Web service



Agenda

■ Overview

■ Demo of the Web and J2EE Tools

■ Extending the Web Tools Platform

■ Call for Participation

■ Q&A



Overview

■ Historically Eclipse is a Java IDE■ Eclipse Web Tools Platform (WTP) project

– formally launched in June 2004– Extends the Eclipse Platform with tools and APIs for Web

and J2EE application development

■ WTP has two subprojects:

–Web Standard Tools (WST)

–J2EE Standard Tools (JST)■ Includes tools for HTML, XML, Web Services, J2EE,

Data■ Includes Server tools for integrating application servers,

e.g. Tomcat, Geronimo, JBoss, WebSphere, WebLogic

WTP Support and Collaboration

■ WTP has support of companies, organizations, academia– BEA, IBM, Oracle, JBoss, ObjectWeb, UBC, UofT

■ WTP collaborates with other open projects and standards bodies– Apache, W3C, WS-I

■ In fact, the WS-I Java test tools are developed by WTP



WTP Roadmap

■ WTP 0.7, July 2005 – End User Tools

■ WTP 1.0, December 2005 – Platform APIs

■ WTP 1.5, June 2006 – Java EE 5.0



Demo

■ Stage 1: expose existing Java class as Web service

■ Stage 2: modify Java class to retrieve data from database

■ Stage 3: modify Web service interface

new!



The Web and J2EE Tools

■ There are several different types of development tools for Web and J2EE development

■ Relational Database■ XML■ Web Services■ Server■ J2EE



Relational Database Tools

■ Connection Wizard– Easily create live

connections to a database server using a JDBC driver

■ Multi-vendor support– Apache Derby– MySQL– DB2




■ Server Explorer – view database elements

including tables, views, stored procedures, and user-defined functions.

– Supports both Live and Offline modes

■ Dependency constraints indicated

■ Browse Data directly from the tables




■ SQL Scrapbook – A SQL utility/editor which can be used to test SQL commands to be

executed to a connected server in the Server Explorer.



XML Tools

■ XML and XSD graphical editors– Assisted editing of XML

content– Constraints enforced– Concise overview of

documents



XML Tools

■ XML Catalog– Customize XML

resource resolution– Based on OAGIS

XML Catalog standard

– Add DTD, XSD, or any XML resource (WSDL, XSL, etc.)



Web Service Tools

■ Graphical WSDL/XSD Editor – Edit your WSDL file without wrestling with the syntax– Visual overview of Web service



Web Service Tools

■ XML Schema, WSDL, and WS-I validators– Ensure your documents conform to standards (WSDL, XSD) and

standard extensions (WS-I)



Web Service Tools

■ WS-I Test Tools integration in the Eclipse Web Tools– Preference for setting the WS-I conformance level



Web Service Tools

■ Wizard to create Web service top-down (from WSDL) and bottom-up (from Java).

■ Wizard creates a Java stub that binds to a Web service.

■ Wizard can optionally configure test client and deployment of your Web service



Web Service Tools

■ Web Service Explorer– Publish/Discover Web

services.– Invoke Web services

dynamically. No code generation required for testing.



Server Tools

■ Server runtime preference page– Add multiple runtimes

■ Multi-vendor support– Apache Tomcat, JBoss,

JoNAS, WebSphere



Server Tools

■ Server control view– Start, stop, publish, debug, configure servers– Shows current server state



J2EE Tools

■ New Web project wizard– Select server– Select J2EE version– Customize environment



J2EE Tools

■ New Servlet wizard– Manage deployment

descriptor– Create Servlet class



J2EE Tools

■ EJB preference page and wizard– Uses XDoclet



Extending the Web Tools Platform

■ WTP is a platform that allows for extension

■ Some interesting WTP extension points– Server– Structured Source Editing



Server Extensions

■ Server Tools – Comes with server adapters for Tomcat, etc.

■ Extension points allow you to…– add other server adapters

■ Useful to…– Create adapters for servers with no current adapter

• e.g. Apache Web Server– Create adapters for custom servers

• e.g. those created as part of course work



Structured Source Editing Extensions

■ Structured Source Editing (SSE)– Editing framework for XML-like file types (XML, JSP, HTML)

■ Extension points allow you to…– Add custom context actions, content assist, syntax highlighting, as-

you-type validation to editors– Configure property page and outline views– Receive notifications of model changes and perform custom

synchronization between model type (eg. EMF and DOM)

■ Useful to…– Create new XML-like editors – e.g. XSL, DocBook, ASP– Customize existing editors by adding function – e.g. new format or

snippet options, publish to blog



Additional API and Extension Points

■ Some additional API and extension points defined for:– Common

• Add custom validators– Web services

• Customize the Web services wizard► Allow for addition of steps in Web service creation► Create Web service deployment for another language, e.g. PHP

• Add support for new binding types to WSDL editor and validator– J2EE

• Add custom steps to artifact import and creation– Data

• Add custom database definitions and wizard pages– XML

• Add actions to graphical XML and XSD editors• Add entries to XML catalog



Call for Participation

■ Become a user and tell your friends and colleagues■ Test and report bugs■ Write tutorials, articles■ Fix bugs■ Contribute enhancements■ Become a committer■ Develop plug-ins based on WTP■ Develop Web and J2EE Curriculum■ Create research projects that extend or use WTP

– Volunteer for the WTP usage study■ Participate at EclipseCon 2006

– http://www.eclipsecon.org



Eclipse WTP Usage Study

■ Goals: – Improve Eclipse IDE user experience– Improve organization of commands in Eclipse base

and Eclipse-based projects■ Minimal commitment:

– Simply use Eclipse WTP for your daily work– About 10 minutes / week to upload data

■ Data collected: – Edits, navigations, commands, but no identifying

information■ For more information:
